            Bug ID: 59425
           Summary: ICE - seg fault building ISL on Windows
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: rtl-optimization
          Assignee: unassigned at gcc dot gnu.org

Preprocessed source file causing ice

Segment fault thrown during build of isl file isl_band.c. Same build works
correctly when using 4.9.0 mingw experimental compiler. Immediate workaround is
to de-optimize.

Preprocessed source file attached. 

Distilled build command:

i686-w64-mingw32-gcc -O3 -march=k8 isl_band.i

Behavior evidently depends on combination of -O3 -march=k8

Using gmp 5.1.3 with fat enabled.

Unfortunately, am unable to obtain a stack trace.

Compiler spew:

sh-3.1$ gcc -v
Using built-in specs.
